Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 14 - 20.09.2015,
Forecast on 21 - 28.09.2015,
Carrington Rotation 2168 (04,57.10.2015)

SUNSPOT-FORMING ACTIVITY OF THE SUN WAS AT THE AVERAGE LEVELS. ESTI-
MATED, WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE IN-
TERNATIONAL SYSTEM (new) WAS W=64+8/-14 (W old =40+4/-9) ON THE VISIB-
LE SOLAR DISK 3-6 SMALL SUNSPOT GROUPS.

THE MIDDLE LEVEL OF THE SUNSPOT-FORMING ACTIVITY IS EXPECTED ON THE
NEXT WEEK. AS ESTIMATED, THE MOST LIKELY WEEKLY AVERAGE VALUE OF THE
RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK
IS W = 030+20/-10.

FLARE ACTIVITY WAS AT THE MIDDLE LEVEL 17 AND 20.09, THE VERY LOW - 14,
AND THE LOW - IN OTHER DAYS. THERE WERE 5 SOLAR FILAMENT EJECTION OC-
CURRENCES THROUGH THE PERIOD. ACCORDING TO THE DATA FROM SOHO AND STE-
REO CORONOGRAPHS >27 CMEs, ONE HALO TYPE AND ONE "PARTIAL HALO II" TY-
PE HAVE BEEN OBSERVED.

THE MINOR SOLAR PROTON EVENT WAS REGISTERED 20.09 AFTER M2.1/SF FLARE:
Pr (<10 MeV): to-~19 UT, max-2045 UT, 3 pfu, continued.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT BEGAN 10/
1020 UT AND OBSERVED ON 10 - 18.09.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY
HIGH LEVEL IS EXPECTED 24 - 27.09.

GEOMAGNETIC CONDITION THE ENTIRE PERIOD CHANGED FROM THE MINOR MAGNETIC
STORM TO UNSETTLED. The FIRST MINOR MAGNETIC STORM (G0, Ams =24, dur. =
12 h.) ACCORDING TO THE BOULDER CENTER DATA AND TWO SUBSTORMS (G1- 6 h.;
G0 - 3 h.) ACCORDING TO THE IZMIRAN DATA 14 -15.09. ONE MORE ALREADY MA-
JOR MAGNETIC STORM (G3, Ams= 65, dur. = 15 h.) ACCORDING TO THE BOULDER
CENTER DATA BEGAN AFTER ARRIVAL OF THE INTERPLANETARY SHOCK WAVE (SI-20/
0645UT) FROM CME C2.6/SF FLARE 18.09. ACCORDING TO THE IZMIRAN DATA THIS
DISTURBATION IS MINOR MAGNETIC STORM - (G1, Ams = 30, dur.= 24 h.) BEGAN
AT THE END OF DAY 19.09 THAT IS CONNECTED WITH PASSING OF THE EARTH OF
THE NTAR EQUATORIAL CORONAL HOLE HIGH-SPEED STREAM, AND THEN, WITH ARRI-
VAL OF THE GEOMAGNETIC IMPULSE AFTER WHICH THE SECOND STAGE OF THE GEO-
MAGNETIC STORM DEVELOPED.

NEXT WEEK ARE POSSIBLE ACTIVE GEOMAGNETIC CONDITIONS 24.09, WHEN EARTH
BE HELD HIGH SPEED SOLAR WIND STREAMS FROM CORONAL HOLES OF NEGATIVE PO-
LARITY NORTHERN HEMISPHERE SUN. PROBABILITY OF MAGNETIC STORM 40%. IN THE
REMAINING DAYS GEOMAGNETIC CONDITIONS EXPECTED UNSETTLED.
